An 18 million year record of vegetation and climate change in northwestern Canada and Alaska: tectonic and global climatic correlates
Abstract We reconstruct long-term vegetation/paleoclimatic trends, spanning the last 18 million years, in Alaska, Yukon and far western Northwest Territories. Twenty-one average percentage spectraExpand

Holocene paleohydrology of central Alberta: testing the general-circulation-model climate simulations
Paleoecological investigations of 28 lakes and bogs provide the basis for a Holocene paleohydrological record for central Alberta. Shallow basins, empty during the early Holocene, began floodingExpand

New Spruce ( Picea spp.) Macrofossils from Yukon Territory: Implications for Late Pleistocene Refugia in Eastern Beringia
New radiocarbon-dated plant macrofossils provide evidence for black spruce ( Picea mariana ) and white spruce ( Picea glauca ) within the unglaciated Yukon Territory at the onset of glacialExpand

The Late Quaternary palaeoenvironmental history of a presently deep freshwater lake in east-central Alberta, Canada and palaeoclimate implications
Abstract The palaeoenvironmental history of Moore Lake, Alberta, Canada (54°30′N; 110°30′W) has been investigated through analysis of pollen, diatoms, total chrysophyte stomatocysts, and sedimentaryExpand
